Background

Mrxvt is a multi-tabbed rxvt clone with XFT, transparent background and CJK support.

Description

Mrxvt mishandles certain escape sequences, some of which allow for shell command execution.

Impact

An attacker with sufficient access to write arbitrary text to the Mrxvt terminal could execute arbitrary code.

Workaround

There is no known workaround at this time.

Resolution

Gentoo has discontinued support for Mrxvt. We recommend that users remove it:

 # emerge --ask --depclean "x11-terms/mrxvt"
OSVersionArchitecturePackageVersionFilename
Gentooanyallx11-terms/mrxvt<= 0.5.4UNKNOWN
